Topographic Surveys in Southern Ontario
A topographic survey records the ground elevations and visible features of your site, so your designer works from real measurements.

Topographic & Existing-Conditions Surveys
Planning a new home, addition, landscape project or commercial development? A topographic survey records the ground elevations and visible features of your site, so your designer works from real measurements. Geo Vision Surveying Inc provides topographic and existing-conditions surveys for residential lots and commercial sites across Southern Ontario. We work with homeowners, builders, architects, engineers and contractors to define the information needed for their project.
What a Topographic Survey Records
We collect site elevations and visible surface features within an agreed survey area. Before fieldwork, we confirm the features to include, required tolerances and deliverables with you or your design team. Underground utilities aren’t visible at the surface. If the scope requires buried utilities to be shown, locates are requested through Ontario Dig Authority (formerly Ontario One Call) before fieldwork, and we survey the locate marks along with the other site features.
Survey Methods and Deliverables
We select surveying methods to suit the site and project requirements. Where appropriate, drone mapping or SLAM LiDAR scanning can support data collection. Coverage, data formats and the level of detail are agreed before work begins.
We can contract an Ontario Land Surveyor on your behalf.
Examples: a topographic survey in Cambridge and a topographic survey in Simcoe. For complex buildings we add SLAM LiDAR scanning, and for larger open sites drone surveying. Once design is approved, we provide construction layout.
Questions about topographic surveys
What does a topographic survey show?
Ground elevations, contours and the visible features on the site, such as buildings, paving, trees, visible utilities and drainage, all tied to a known elevation. Buried utilities are shown from locate marks only when the scope requires them.
When do I need a topographic survey?
Usually before design starts. For a new home, an addition, an infill build, landscaping or a pool, your designer or engineer needs existing grades and features to work from.
